The Rugby Championship kicks off for 2017 this weekend, starting with old foes New Zealand and Australia facing off in a match that doubles as the first of the three-match Bledisloe Cup series. So where will the two matches be played, what time do they kick off, and who will feature?

Broncos apologise for Trbojevic tweet

Brisbane have apologised to NRL rivals Manly after they were forced to take down a social media post and story on their website lauding the tackle that injured Tom Trbojevic as a "great play".

The tweet linked to an explanation why David Mead's tackle was within the rules when he controversially took out the Sea Eagles fullback in the 63rd minute of Saturday night's clash at Suncorp Stadium.

It also bore the hashtag #TrueStrength, a slogan of sponsors Optimum Nutrition.

Trbojevic suffered a syndesmosis injury to his left ankle and a medial ligament sprain to his left knee when Mead landed on him, ruling him out for six to eight weeks and ending his NSW State of Origin hopes.

The Broncos were roundly condemned on social media, with Trbojevic's teammate Darcy Lussick among those who criticised them with more than a hint of sarcasm.

Unbeaten fighter Floyd Mayweather has promised to repay any losses talk-show host Jimmy Kimmel suffers if he loses his fight against Conor McGregor.

A Broncos spokesperson said the club was trying to outline the reasons why Mead had not been penalised after receiving multiple inquiries from supporters over the incident but recognised it came across poorly.

The Broncos also called Manly to apologise.

Mead was not penalised because the 'tackling in the air' rule offers protection to players only when the ball is caught on the full - not when it bounces first, as was the case with Trbojevic.

The Broncos scored off the play and took the lead before finishing up as 24-14 winners.
